The SmartlockPro self-test GFCI tests itself even if you forget. Designed to meet the latest UL standard for auto-monitoring (self-test) our complete line of self-test GFCIs periodically conduct an automatic internal test to confirm that it can respond to a ground fault.

The SmartlockPro self-test GFCI is the smart choice in ground fault circuit interrupter protection. Features For an added layer of protection, the GFCI regularly conducts an automatic internal test to confirm that it can respond to a ground fault Provides continuous ground fault protection - detects and trips on actual ground fault even when self-test is being conducted Status indicator light provides simple, intuitive feedback on power and protection status as well as indication of line/load reversal Patented lockout action prevents reset if GFCI is damaged and cannot respond to a ground fault Slim, shallow design - reduced depth makes it easier to install in any electrical box, even shallow ones Wallplates not included USA SHIPPING estimates delivery times and we work to get your item to you as quickly as possible and within those times, but please know it may take slightly longer than the estimate.
